I3 is a category of diamond that in the past would only have been used for industrial diamonds. (e.g. they would be ground up and used to make saw blades) However because of the demand for cheap diamonds, I3 diamonds are now being cut and used in jewelry. This is why the prices for certain types of diamond jewelry have become incredibly cheap. Diamonds are graded as follows: FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, I3 The grading description for I3 is as follows: "I3 diamonds have large and extremely easy to see inclusions that typically impact the brilliance of the diamond, as well as having inclusions that are often likely to threaten the structure of the diamond."
